A picture of the puppy shows it is unusually skinny with tattered fur. WFMZ reports that medical tests revealed Annie had open wounds, anemia from fleas, weighed just six pounds and had "literally no fat."

A Facebook page called "Hope for Orphan Annie" says that the dog has had trouble holding down food since being recovered, and is being fed small meals multiple times a day along with medicine for her stomach.

Pennsylvania State Police and Dog Law Enforcement officials are investigating it as a cruelty situation, and a photo taken from surveillance footage shows a woman who authorities believe left the animal.

Police are looking for this woman who they say dropped off an "emaciated" poodle outside a Lehigh Valley animals clinic. (Quakertown Veterinary Clinic / Facebook)

Anyone with information on the woman or Annie is asked to call the Peaceable Kingdom tip hotline at 610-709-6454 or Dog Law Enforcement Officer Orlando Aguirre at 484-223-9107.
